VEHICLE SAN D-BOX.

SPECIFICATION forming part of Letters Patent No. 769,182, dated September 6, 1904;.

Application filed November 30, 1906. Serial No. 183,225. (No model.)

To all whom it may concern: I

Be it known that I, GEORGE M. PORTER- FIELD, a citizen of the United States, residing at Winnsboro, in the. county of Wood and State of Texas, have invented a new and useful Vehicle Sand-Box, of which the following is a specification.

This invention relatesto an improved sand band or guard for vehicle-wheels, and has for its object to provide a simple, inexpensive, and efficient device of this character by means of which sand, dust, and other foreign matter are effectually prevented from obtaining access to the journal or wearing parts of the axle.

A further object of the invention is to provide means for truing the wheel and taking up any lost motion thereof incident to continuous wear on the spindle or boxing.

A still further object is to form one end of the hub-holding nut with an annular flange adapted to fit snugly within the cap on the front end of the hub and bear against the boxing, the opposite end of said nut being curved or rounded, so as to deflect the sand and dust and prevent the same from entering the journal.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in form, proportion, and minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figure 1 is a longitudinal sectional View of a hub and a portion of the axle of a vehicle, showing my improved sand band or guard; and Fig. 2 is a perspective view of the axle, sand-band, and

securing-nut. 7

Similar numerals of reference indicate corresponding parts in both figures of the drawings.

1 designates an axle of the ordinary form and construction, and 2 the spindle,,provided with an annular shoulder 3, defining a reduced threaded extension 4;. The axle is preferably rectangular incross-section, as shown, and

mounted on said axle at a point adjacent the spindle 2 is an adjustable sleeve 5, which constitutes the sand band or guard and prevents sand, dust, 'and other foreign matters from entering the journal atthe rear end of the hub. The sleeve 5 is provided with an inwardly-extending flange 6, defining a reduced collar 7, having an annular groove 8 formed therein, a seating groove or channel 9" being formed at the juncture of the flange and collar for the reception of the boxing 10 of a wheelhub- 11, as shown. The rear portion of the flange 6 is rounded, as shown in Fig. 2, so as to prevent particles of sand, dust, and the like from lodging on the surface thereof .and

eventually working their way to the journal. The flat bottom surface of the sleeve 5 is provided with a transversely-disposed slot or recess 12, in which is seated a perforatedplate 13, the threaded .ends of astrap or clip 14, passing through the perforations in' the clip and engaging suitable nuts, serving to clamp the sleeve in positionon the axle. The sleeve 5 is also provided with a threaded opening 15 for the reception of a clamping-screw 16, which forms an additional means of securing the sleeve in place. Threaded on the extens'ion 4: of the spindle is a hub-securing nut 17, provided at one end with an annular flange or collar 18, which fits snugly withinthe hub-cap 19, as shown, soas to prevent ingress of sand at the front end of the hub. The opposite end of the nut 17 is provided with a'semicircular head 20, which completely closes the opening formed by the cap 19 and serves to deflect any sand or dirt taken up by the wheel and falling thereon when the vehicle is in motion and also serves to give a neat finish to the hub. A transversely-disposed groove or slot 21 is preferably formed in the head 20, so as to permit the nut to be readily removed with a flat piece of iron or the like and Without the necessity of using a wrench or similar tool. The interior of the nut 17 is provided with an annular recess 22 for the reception of a washer 23, which bears against the front end of the hub-boxing, as clearly shown in Fig. 1' of the drawings.

The slot 21 preferably communicates with the threaded bore 23 of the nut 17, and arranged within the bore 23 and seated against a shoulder 24:, formed in the end thereof, are one or more washers 25, which bear against the end of the spindle and serve to take up the wear on said spindle and boxing. The nut 17 is also provided with a shoulder 26, adapted to engage the shoulder 3 on the spindle when the washers 25 are removed and said nut adjusted. By having the washers 25 arranged in the bore 23 and normally in contact with the end of the spindle the wheel is prevented from wabbling, while any lost motion incident to Wear on the spindle or boxing may be quickly remedied by removing one or more of the washers and adjusting the nut, as will be readily understood.

Should any particles of sand be forced past the semicircular head at the front end of the hub, they will lodge on the intermediate squared portion of the nut, being prevented from entering the journal by means of the flange or collar 18, while the sand is effectively excluded from the rear end of the hub by the sand band or guard, as before stated.

The sleeve 5 and nut 17 being both adjustable, the several wheels of the vehicle may be readily trued or alined, while any lost motion due to the wear on the boxing may be quickly remedied by adjusting the nut 17.

From the foregoing description it will be seen that I have provided an extremely simple and effective means for preventing the entrance of sand and other foreign matter to the wearing parts of the axle at both the front and rear end of the hub.

Having thus described the invention, what is claimed is 1. The combination with an axle having a hub-receiving spindle and provided with a sand-band, of a nut having a semicircular head and intermediate squared portion carried by the spindle, the head of said nut being provided with a transversely-disposed tool-receiving recess and the opposite end of the nut with an annular flange adapted to engage the hub.

2. The combination with an axle having a hub-receiving spindle and. provided with a sand-band, of a nut having a semicircular head and intermediate squared portion carried by the spindle, a flange on the inner end of the nut adapted to engage the hub, and washers mounted in the bore of said nut for engagement with the end of the spindle.

3. The combination with an axle having a hub-receiving spindle and provided with a sand-band, of a nut carried by the spindle and provided with a semicircular head adapted to engage the inner face of the hub-cap. said nut being provided with an intermediate squared portion and a terminal flange of the same diameter as the head of the nut, there being a transverselydisposed tool-receiving recess formed in the semicircular head of said nut.

In testimony that I claim the foregoing as my own I have hereto aliixed my signature in the presence of two witnesses.
